What Is Base64?

Base64 is an encoding method that converts data into a text-based format using a limited set of characters. It is commonly used when data needs to be transported or embedded in systems that primarily handle text.

What Base64 does

It encodes binary or text data into a standardized text representation.

This is useful for things like email attachments, API payloads, tokens, and data URLs.

What Base64 is not

Base64 is not encryption.

It does not hide secrets securely. Anyone can decode it easily.

Common use cases

  • Embedding small files in data URLs
  • Encoding credentials or tokens in transit formats
  • Moving binary data through text-only systems

Encode and decode

Use a simple tool when you need to convert text to Base64 or decode it back to readable data.
